On final for a landing and you are short and near stall--punch the throttle and hope you can go around.
You overshot the field on landing and you need to abort.
You decided to hover and want a vernier change in thrust to hold altitude.
I own a DX9 and one nice feature is the THROTTLE...
Pushing the limit, I decided to test a dual 70mm's thrust vectoring nozzle plane to see how well thrust vectoring provides roll, pitch and yaw WITHOUT ANY MOVING SURFACEs on the plane. All controls are directed to the thrust vectoring nozzles.
2 nozzles up will produce pitch
